inch in width. Inasmuch as the Width of the bars does not aiect their ability to pick up the hairs, it is desirable to keep the bars quite narrow to avoid obstructing a large portion of the area of the shear plate I3.

As illustrated in Figure 3, the bars I6 of the member I5 may be slightly undercut at their edges I'I in order to lift and project the hairs into the apertures adjacent thereto. Thus, as the shearing head is passed over the face the bars I6, in all positions of the shearing head, can engage hairs lying flatly against the skin, lift them upwardly slightly and project them into the apertures in the shear plate I3. The ripple formed in the skin by contact with the bars also tends to straighten up the hairs and project them outwardly from the skin. While the bars I6 have been illustrated as undercut, satisfactory operation may be obtained with substantially rectangular bars or bars that have slightly curved outer surfaces. However, the lateral edges of the bars are, in all forms of the invention, substantially perpendicular to the surface of the shear plate I3.

The form of the invention disclosed in Figure 4 is illustrated as applied to a shearing head having a cylindricalor semi-cylindrical skin contacting portion. The shear plate 20 is formed of a curved strip of metal having apertures 2| through which hairs are projected to be severed by a cutter blade 22 disposed interiorly thereof. In order to lift and project long hairs or hairs lying atly against the skin into the apertures 2|, I have provided longitudinally extending bars 23 on the outer surface of the shear plate 2l). These bars, like those disclosed in Figures l to 3, may be about 11g of an inch in width and about .010 of an inch in thickness. By spacing these bars at about 1A; inch intervals along the shear plate 20 they will be able in all positions of the shear plate 2B to pick up and project the hairs through the apertures 2| for severance by the blade 22.

Another form of the invention is disclosed in Figure 5 which is likewise applied to a cylindrical or semi-cylindrical shearv plate 30. TheA shear plate 30 is provided with a plurality of apertures 3| through which hairs may be projected tobe severed by a cutting blade disposed interiorly thereof. In this form of the invention the hairlifting bar 32 extends diagonally or spirally across the outer surface of the shear plate 30 and thus can engage hairs no matter what the position of the shear plate 30 with respect to the skin. Therefore, the bar 32, similarly to the pick-up bars previously described, tends to lift and project the hairs through the apertures 3l where they may be severed by the inner cutter member.

From the foregoing description of typical forms of the invention, it will be apparent that I have provided a simple and effective means for rendering shaving devices of the character described above capable of severing long hairs and hairs which lie flatly against the skin.

It will be understood that many variations in the arrangement of the hair-lifting and guiding bars may be made without departing from the invention so long as the principles underlying this invention are embodied in these variations lof the shaving devices. Accordingly, the above embodiments of the invention should be considered as illustrative only and not as limiting the scope of the following claims.
